我是那種臉上時不時會起那種發炎很厲害的大型青春痘的那種人，沒黑頭沒白頭沒粉刺，直接一個很大很痛的包包。這個果酸水楊酸混合的凝露不能說是奇跡吧，但卻是對那種大包比較有效，可以把會發上一個月的包包縮短到一個星期，然後把痘印的消除時間從半年縮短到一個月，所以還是相當感謝它的。It works well for my nodules/papules, flattening them by a weak and getting rid of the redness by a mouth. I don't think it's miraculous, as it really doesn't help preventing anything, but it is effective and get my acne-prone skin under control. Don't know whether it works for blackheads or whiteheads, because I usually don't have them.
